    Puget Sound Region Final Comprehensive Climate Action Plan

    The Puget Sound Region Final Comprehensive Climate Action Plan, published December 1, 2025 by the Puget Sound Clean Air Agency, outlines greenhouse gas reduction strategies for King, Kitsap, Pierce, and Snohomish Counties in the Seattle-Tacoma-Bellevue metropolitan area. The plan covers six sectors—Built Environment, Transportation, Municipal Solid Waste and Wastewater, Natural and Working Lands, Refrigerants, and Consumption—with goals, emission projections, and workforce planning analysis. Note that this document focuses on regional climate and air quality policy rather than Sea-Tac Airport noise regulations specifically.

    Quiet Communities Act of 2023 (H.R. 4178)

    H.R. 4178, the Quiet Communities Act of 2023, is a bill introduced in the U.S. House of Representatives on June 15, 2023, that seeks to reestablish the EPA's Office of Noise Abatement and Control, which has received no funding since 1982. The bill highlights the serious health impacts of noise pollution — including hearing loss, cardiovascular disorders, sleep deprivation, and learning deficits in children — affecting millions of Americans exposed to noise from aircraft, vehicular traffic, and other sources. Because the EPA remains legally responsible for enforcing noise regulations while lacking an active office to do so, and because federal law limits state and local governments from regulating many noise sources, the bill argues that noise abatement programs across the country have effectively lain dormant.

Read This!

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
